NTRU cryptosystem was proposed by J. Hoffstein, J.Pipher and J.H. Silverman in 1996, whose security is related to the hardness of finding sufficient short vectors in NTRU lattice with dimension 2N. Many researchers conjecture that the private key vector is indeed the shortest vector in the lattice in most cases.

NTRUReEncrypt: An Efficient Proxy Re-Encryption Scheme Based on NTRU

WebNTRU problem is equivalent to finding a short vector in the NTRU lattice, which has been conjectured to be a hard problem. The hardness lies with the fact that if we take two random small polynomials , then is indistinguishable from random in .
